mod_compat_roles: Fix attempt to index a nil value #1847
permissions[] is not a map with role names as keys since 817bc9873fc2
but instead a level with host names were added. This was likely an
oversight.
Refactored towards railroad.

summary: Limit presence stanzas to save traffic
...
Introduction
============
For most people 'presence' (status changes) of contacts make up most of
the traffic received by their client. However much of the time it is not
essential to have highly accurate presence information.
This module automatically cuts down on presence traffic when clients
indicate they are inactive (using the [CSI protocol](mod_csi.html)).
This is extremely valuable for mobile clients that wish to save battery
power while in the background.
Configuration
=============
Just load the module (e.g. in modules\_enabled). There are no
configuration options.
Compatibility
